Conjugate Heat Transfer of Two Forced Convection Boundary Layers in Counterflow

In this study, the conjugate heat transfer problem of two laminar forced convection boundary layers of counterflow on conductive wall sides is analyzed in a dimensionless form by employing the integral method. The resultant main differential equations are solved numerically by using the well-known fourth-order Runge-Kutta numerical technique. The main dimensionless parameters affecting the thermal interaction process between two convection layers are deduced from the analysis. These parameters give a measure of the relative importance of interactive convection and conduction heat transfer modes. Mean Nusselt number data are obtained for a wide range of these affecting parameters.
